My DMV Graphics Design

So the place is closed on weekends however I called just to make sure the information is accurate. To my surprise someone answered the phone and said «hello» I asked if they were open and the person sounded confused and asked who I was trying to reach. Long story short the owner I’m guessing said she had her store number forwarded to her cell phone and this number is also used for another business.
#1 this is unprofessional especially if the store is closed. What’s the post of having the # forwarded if the store is closed.
#2 try answering the phone professionally and properly as for your first impression only comes around once.
I love shopping in my neighborhood and I love shopping at small business but this is the usual problem with doing so. Limited hours and lack of service send me right to box box stores.
